DB Perma-Pak


The T648 DB Perma-Pak packer is a versatile permanent seal bore packer which may be set on electric line or hydraulically depending on requirements. The DB Perma-Pak has a large upper seal bore allowing the largest possible I.D. through the packer and seals for completions requiring large tubing sizes. It is particularly suitable for use in stimulation jobs where excessive pressure and/or temperature conditions are anticipated. It can be converted to a temporary bridge plug with the addition of a knockout, pump out or threaded plug for temporary lower zone isolation.
